<u>Answer:</u>
Cost of package of paper = 4$
Cost of stapler = 7$
<u>Explanation:</u>
Consider the cost of package of paper = x and that of stapler = y.
Now, we are given that cost of 3 paper packages and 4 staplers = 40$
Hence we get, 3x + 4y = 40 as 1st equation.
we are also given, cost of 5 paper packages and 6 staplers = 62$
Hence, the second equation is 5x + 6y = 62
Now, solving the two equations by method of elimination, we first equate coefficients of any one variable say x by multiplying 1st equation by 5 and second by 3 we get ->
15x + 20y = 200
15x + 18y= 186
Subtracting the two we get y = 7 and substituting this value of y in first equation we get x = 4
which gives the required cost of one paper package = x = 4$
and one stapler = y = 7$

Answer:</h2>
<h2>Step-by-step explanation:</h2>
<u>First step</u> : Multiply
<u>Second step</u> : Add
9 × 2 + 3 + 6 + 9 = 36
The correct answer is 2.
X=1
5=-4y+4
4y=-1
y=-1/4
x=2
10=-4y+4
4y=-6
y=-3/2
x=3
15=-4y+4
4y=-11
y=-11/4
The complete question is;
A paintball court charges an initial entrance fee plus a fixed price per ball.
P represents the total price (in dollars) as a function of the number of balls used n.
P = 0.80n + 5.50
How much do 10 balls cost?
Answer:
Cost of 10 balls = 8 dollars
Step-by-step explanation:
We are told that;
total price in dollars is given as a function of the number of balls
p = 0.8n + 5.5
Where n is number of balls.
We are told that the price above is price of number of balls plus entrance fee.
Thus, 5.5 dollars is the entrance fee while 0.8n dollars is the price for n number of balls.
Thus,for 10 balls,
Price of 10 balls will be 0.8 x 10 = 8 dollars
Start by factoring an x term out of the equation:
x(x-11)=0
Now, you can set each term equal to zero and solve for x:
x=0
x-11=0
x=11
x={0, 11}
Hope this helps!!
